A uniform ladder of length L and mass m leans against a frictionless vertical wall, making an angle of 49° with the horizontal. The coefficient of static friction between the ladder and the ground is 0.45. If your mass is four times that of the ladder, how high can you climb before the ladder begins to slip?

A nonuniform ladder is leaned against a frictionless wall. The ladder has a mass of 30 kg, a length of 10.0 m, and makes a 60° angle with the ground. The coefficient of static friction between the ladder and the ground is 0.42. Assume g = 10.0 m/s^2 a. If a 75 kg firefighter is able to climb 90% of the way up the ladder before it begins to slip, where is the center of mass of the ladder located...

A ladder of mass M and length 3.00 m rests against a
frictionless wall at an angle ? = 50° to the horizontal as in the
figure below. The coefficient of static friction at the floor is
0.600. What is the maximum distance along the ladder a person of
mass 12M can climb before the ladder starts to slip?

A uniform ladder 12 meters long rests against a vertical frictionless wall, as shown in the figure. The ladder weighs 400 N and makes an angle θ = 51° with the floor. A man weighing 874 N climbs slowly up the ladder. When he is 78 m from the bottom of the ladder, it just starts to slip. What is the coefficient of static friction between the floor and the ladder? 7.8 m
